301 onward      4.5/unit

Software used:- Notepad, Command prompt

Program coding:-

class Bill 

{ 

        public static void main(String args[]) 

        {

  

int units;

units = Integer.parseInt(args[0]);

double bill=0;

        if(units<100)

bill=units*1.0;

else if(units<=200)

bill=100+(units-100)*1.5;

else if(units<=300)

bill=100+150+(units-200)*3.5;

else if(units>300)

bill=100+150+350+(units-300)*4.5;

      System.out.println("Bill is"+ bill); 

   } 

}
